Provider costs of treating opioid dependence with extended-release buprenorphine in Australia.

INTRODUCTION: The costs of providing medication-assisted treatment for opioid dependence can determine its scale of provision. To provide estimates of the costs of extended-release buprenorphine (BUP-XR), we performed a bottom-up costing analysis of provider operational treatment costs. METHODS: Data were collected in a single-arm open label trial of BUP-XR injections conducted in specialist public drug treatment services and primary care private practices in three Australian states (the CoLAB study). The unit costs of resources used for each activity were combined with quantities used at each participating facility to arrive at the average annual cost per client. RESULTS: One hundred participants across the six health facility sites received monthly subcutaneous BUP-XR injections administered by a health-care practitioner. The average cost of providing 1 year of treatment per participant was $6656 ($6026-$8326). Screening cost (initial assessment and medical history) was $282 while monthly follow-up appointments cost $531 per client. The main cost driver was the monthly treatment costs accounting for 79% of the average annual client cost, with medication costs comprising 95% of this cost. DISCUSSION AND CONCLUSION: With medication costs making up the largest proportion of treatment costs, treatment using BUP-XR has the potential to free up other health system resources, for example, staff time. The costs reported in this study can be used in an economic evaluation to estimate the net benefit or cost-effectiveness of BUP-XR especially when compared to other opioid agonist treatments.

Integration of a facilitated access pathway for contraception into alcohol and other drug treatment services: A cohort study comparing metropolitan and regional settings.

INTRODUCTION: Women who attend alcohol and other drug (AOD) services experience higher rates of unintended pregnancy, and access less contraception, than the general population. This study aims to observe contraceptive initiation and use after contraception services were offered at metropolitan and regional AOD services. METHODS: Clinical staff were provided contraception education. One hundred women aged 16-49 were recruited from two services between 2017 and 2021. Women completed a questionnaire on their obstetrics and gynaecological history, pregnancy plans and contraception use. Women were provided education on contraception options and offered referral to a contraception pathway. The primary outcome was initiation of highly reliable contraception; secondary outcomes were the types of contraception initiated, and contraception use and pregnancy at 12 months. We compared the initiation of contraception across the two study sites. RESULTS: At baseline, 91% of women were not planning a pregnancy within 12 months, with 21% of these using highly reliable contraception. Of all women not planning a pregnancy, 28% initiated highly reliable contraception via the pathway (2% metropolitan, 51% regional, p < 0.001), with intrauterine devices being the most frequent method initiated (15%). At 12 months, 44% were using highly reliable contraception and 15% had recorded pregnancies. DISCUSSION AND CONCLUSIONS: Contraception pathways for women in AOD treatment can improve initiation of highly reliable methods of contraception, although pregnancy rates were still high and there were large differences between the study sites. Care navigation and clinical champions are some potential facilitators to contraception access, and understanding additional barriers to access may be useful.

Implementation of time-limited parenteral hydromorphone in people with treatment-resistant injecting opioid use disorder: a protocol for a single-site, uncontrolled, open-label study to assess feasibility, safety and cost.

INTRODUCTION: Supervised injectable opioid treatment (SIOT) is an evidence-based intervention targeting opioid-dependent people for whom existing treatments have been ineffective. This project will primarily assess the feasibility and the acceptability of time-limited SIOT using injectable hydromorphone delivered in an existing Australian public opioid treatment programme, with secondary outcomes of safety, cost, changes in drug use and other health outcomes. If feasible, the goal is to scale up the intervention to be more widely available in Australia. METHODS AND ANALYSIS: Between 20 and 30 participants will be offered two times per day hydromorphone to inject under direct observation, in addition to their current opioid agonist treatment (OAT), for up to 2 years. At the end of 2 years of supervised hydromorphone treatment, participants will be continued on standard OAT only. Informed consent will be obtained from all participants included in the study. This is a single-site, uncontrolled, open-label study where quantitative and qualitative interview data will be collected at baseline, 12 months and lastly at 3 months following their final hydromorphone dose. The main outcome measures are feasibility, as assessed by recruitment, retention and participation in treatment, and acceptability to participants, clinic staff and other stakeholders assessed by qualitative interviews. Secondary outcome measures of safety, as assessed by adverse events, and cost will also be assessed, as well as a range of other drug and health outcomes. ETHICS AND DISSEMINATION: This study received ethical approval from the St Vincent's Hospital Human Research Ethics Committee (2019/ETH00418). This will be the first study of time-limited SIOT in the Australian setting. All results will be submitted to peer-reviewed journals, scientific conferences and local practice meetings. A preliminary report on outcomes will also be presented to local health policy makers. A consumer and community forum will also be held to feedback results to a broader audience. TRIAL REGISTRATION NUMBER: ACTRN12621001729819.

Sociodemographic and Health Factors of the Alcohol Treatment-seeking Population in New South Wales, Australia.

OBJECTIVES: Although factors associated with alcohol use have been researched at a population level, descriptions of the alcohol and other drug (AOD) treatment-seeking population in New South Wales (NSW), Australia, are limited. This study addresses this gap by analyzing sociodemographic and health characteristics in the NSW AOD treatment-seeking population. METHODS: Self-reported Australian Treatment Outcomes Profile data on substance use, health ratings, and sociodemographic factors were acquired from public AOD services (offering services from counseling to ambulatory/inpatient withdrawal management) in 6 administrative health districts from 2016 to 2019 (n = 14,287). Gaussian and multiple logistic regressions were conducted to examine associations between these factors and alcohol consumption quantity. RESULTS: Data were analyzed for patients seeking treatment for alcohol consumption specifically (n = 5929; median age, 44 years; 65% male). Valid alcohol consumption data were available for 5460 patients, among whom the mean volume of alcohol consumed was 311 standard drinks (3110 grams of ethanol) over the past 28 days and 15 standard drinks (150 grams of ethanol) per occasion. Higher volumes were consumed by males and those with recent experiences of violence and/or injecting drug use. Caring for children younger than 5 years and having above-median health ratings were associated with lower alcohol consumption. CONCLUSIONS: This study contributes to the characterization of the NSW public AOD treatment population and identifies associations between alcohol consumption, sociodemographic factors, and health ratings among people seeking treatment for alcohol consumption. Findings point towards multilevel assessment and comprehensive interventions for people engaging in treatment for alcohol use. Future research should address barriers to treatment.

Medical cannabis use in Australia seven years after legalisation: findings from the online Cannabis as Medicine Survey 2022-2023 (CAMS-22).

BACKGROUND: Cannabis was legalised for medical purposes in 2016. Uptake was initially slow, but since 2019 there has been a large increase in the number of Australians who have been prescribed cannabis for medical reasons. Yet a significant number of consumers continue to treat their medical conditions via illicitly-sourced cannabis. Little is known about how these two groups of medical cannabis consumers differ. METHODS: The anonymous Cannabis-As-Medicine Survey 2022-2023 (CAMS-22) was available for completion online from December 2022 to April 2023 to adult Australians who had used cannabis to treat a medical condition in the previous year. Recruitment occurred through social media, consumer forums, and medical practices. Questions included demographic characteristics, patterns of cannabis use, conditions treated, and self-rated effectiveness. RESULTS: Of the 3323 respondents included in these analyses, 2352 (73%) mainly used prescribed medical cannabis, 871 (27%) mainly used illicit. Prescribed users were significantly more likely than illicit users to have had their health condition diagnosed (OR = 1.7, 95% CI 1.3, 2.2), to consume their cannabis via oral (OR = 1.9; CI 1.5, 2.4) or vaporised (OR = 5.2; CI 4.0, 6.8) routes, and to be sure of the composition of their medical cannabis (OR = 25.0; CI 16.7, 50.0). Prescribed users were significantly less likely to have used cannabis non-medically before medical use (OR = 0.6, CI 0.5, 0.7), consume cannabis via smoked routes (OR = 0.2, CI 0.1, 0.2), and to report any side effects (OR = 0.1; CI 0.1, 0.2). The most common conditions among both prescribed and illicit users were pain (37%), mental health (36%), and sleep (15%) conditions. Prescribed users were significantly more likely to use cannabis to mainly treat a pain (OR = 1.3; CI 1.1, 1.5) or sleep condition (OR = 1.4; CI 1.1, 1.7) and less likely to treat a mental health condition (OR = 0.8; CI 0.7, 0.9). There were no between-group differences in effectiveness with 97% saying medical cannabis had improved their symptoms. CONCLUSIONS: From a harm-reduction perspective there is much to recommend prescribed medical cannabis; it has fewer side-effects than illicit, is used more safely (oral or vaporised versus smoked routes), gives consumers greater certainty regarding the composition and quality of their medicine, and does not risk exposure to the criminal justice system. Of concern, however, is the apparent willingness of prescribers to prescribe for indications for which there is limited evidence of efficacy, such as mental health and sleep conditions.

An International, Multidisciplinary Consensus Set of Patient-Centered Outcome Measures for Substance-Related and Addictive Disorders.

Background: In 1990, the United States' Institute of Medicine promoted the principles of outcomes monitoring in the alcohol and other drugs treatment field to improve the evidence synthesis and quality of research. While various national outcome measures have been developed and employed, no global consensus on standard measurement has been agreed for addiction. It is thus timely to build an international consensus. Convened by the International Consortium for Health Outcomes Measurement (ICHOM), an international, multi-disciplinary working group reviewed the existing literature and reached consensus for a globally applicable minimum set of outcome measures for people who seek treatment for addiction. Methods: To this end, 26 addiction experts from 11 countries and 5 continents, including people with lived experience (n = 5; 19%), convened over 16 months (December 2018-March 2020) to develop recommendations for a minimum set of outcome measures. A structured, consensus-building, modified Delphi process was employed. Evidence-based proposals for the minimum set of measures were generated and discussed across eight videoconferences and in a subsequent structured online consultation. The resulting set was reviewed by 123 professionals and 34 people with lived experience internationally. Results: The final consensus-based recommendation includes alcohol, substance, and tobacco use disorders, as well as gambling and gaming disorders in people aged 12 years and older. Recommended outcome domains are frequency and quantity of addictive disorders, symptom burden, health-related quality of life, global functioning, psychosocial functioning, and overall physical and mental health and wellbeing. Standard case-mix (moderator) variables and measurement time points are also recommended. Conclusions: Use of consistent and meaningful outcome measurement facilitates carer-patient relations, shared decision-making, service improvement, benchmarking, and evidence synthesis for the evaluation of addiction treatment services and the dissemination of best practices. The consensus set of recommended outcomes is freely available for adoption in healthcare settings globally.

The dynamics of more-than-human care in depot buprenorphine treatment: A new materialist analysis of Australian patients' experiences.

BACKGROUND: Long-acting injectable depot buprenorphine has become an important treatment option for the management of opioid dependence. However, little is known about patients' experiences of depot buprenorphine and its embodied effects. This qualitative study aims to explore patients' experiences of depot buprenorphine treatment, including how it feels within the body, experiences of dosing cycles across time, and how this form of treatment relies on wider ecologies of care beyond the clinical encounter. METHODS: Participants were recruited from sites in Sydney, regional New South Wales, and Melbourne, Victoria, Australia. Thirty participants (16 men, 14 women) participated in semi-structured interviews. Participants had histories of both heroin and prescription opioid consumption, and opioid agonist therapy including daily dosing of buprenorphine and methadone. RESULTS: Our analysis illuminates: (1) how patients' expectations and concerns about treatment are linked to past embodied experiences of withdrawal and uncertainty about the effectiveness of depot buprenorphine; (2) the diverse meanings patients attribute to the depot buprenorphine substrate 'under the skin'; and, (3) how depot buprenorphine is embedded within wider ecologies of care, such as counselling and social supports. CONCLUSION: Our analysis destabilises commonplace assumptions about a linear, causal relationship between the pharmacological action of depot buprenorphine and experiences of treatment. Instead, it highlights patients' variable experiences of depot buprenorphine, tracing the everyday practices, embodied feelings, expectations and wider networks of care that shape patient experiences. We conclude with some reflections on the implications of our analysis for alcohol and other drug treatment, specifically how they might inform the design of client education materials and care.

Participant experiences in a pilot study for methamphetamine withdrawal treatment: Implications for retention.

INTRODUCTION: There is little knowledge of the perspectives of people who use methamphetamine and have participated in clinical trials, and none for interventions not intended to address abstinence. A better understanding of these experiences could lead to more patient centred clinical trial design. This study seeks to understand the experiences of people who completed a clinical trial of lisdexamfetamine for the treatment of acute methamphetamine withdrawal. METHODS: Thematic analysis of open-ended, semi-structured interviews with eight people who participated in an inpatient clinical trial of lisdexamfetamine for acute methamphetamine withdrawal. Interviews were conducted between days 3 and 6 of admission to an inner-city Sydney hospital. RESULTS: Participants described how research procedures, the research setting, and the investigational product affected their experiences while enrolled in a clinical trial. Of particular importance to participants were transparent and low burden trial procedures, a welcoming trial environment, trusting relationships and effective communication, which were linked with the participants' subsequent decision to remain enrolled in the trial. DISCUSSION: The experiences of participants in this clinical trial can be distilled into four meta-themes: agency, caring-trust, safety, and communication. Participants spontaneously linked these experiences with a capacity to remain enrolled in the study. By considering the experiences of trial participants in clinical trial design, researchers can improve the experiences of future trial participants and facilitate their choice to remain enrolled in clinical trials.

Measuring Objective and Subjective Sleep during Lisdexamfetamine Treatment of Acute Methamphetamine Withdrawal: A Feasibility Study.

INTRODUCTION: Sleep disturbance is common during methamphetamine (MA) use and withdrawal; however, the feasibility of combined subjective-objective measurement of sleep-wake has not been shown in this population. Actigraphy is a well-established, non-invasive measure of sleep-wake cycles with good concordance with polysomnography. This study aimed to investigate the feasibility and utility of using actigraphy and sleep diaries to investigate sleep during MA withdrawal. METHODS: We conducted a feasibility and utility study of actigraphy and sleep diaries during a clinical trial of lisdexamfetamine for MA withdrawal. Participants were inpatients for 7 days, wore an actigraph (Philips Actiwatch 2) and completed a modified Consensus Sleep Diary each morning. Participants were interviewed between days 3-5. RESULTS: Ten participants (mean age 37 years, 90% male) were enrolled. No participant removed the device prematurely. Participants interviewed (n = 8) reported that the actigraph was not difficult or distracting to wear or completion of daily sleep diary onerous. Actigraphic average daily sleep duration over 7 days was 568 min, sleep onset latency 22.4 min, wake after sleep onset (WASO) 75.2 min, and sleep efficiency 83.6%. Sleep diaries underreported daily sleep compared with actigraphy (sleep duration was 56 min (p = 0.008) and WASO 47 min (p < 0.001) less). Overall sleep quality was 4.4 on a nine-point Likert scale within the diary. CONCLUSIONS: Continuous actigraphy is feasible to measure sleep-wake in people withdrawing from MA, with low participant burden. We found important differences in self-reported and actigraphic sleep, which need to be explored in more detail.

Neuroimaging studies of cannabidiol and potential neurobiological mechanisms relevant for alcohol use disorders: a systematic review.

The underlying neurobiological mechanisms of cannabidiol's (CBD) management of alcohol use disorder (AUD) remains elusive.Aim We conducted a systematic review of neuroimaging literature investigating the effects of CBD on the brain in healthy participants. We then theorise the potential neurobiological mechanisms by which CBD may ameliorate various symptoms of AUD.Methods This review was conducted according to the PRISMA guidelines. Terms relating to CBD and neuroimaging were used to search original clinical research published in peer-reviewed journals.Results Of 767 studies identified by our search strategy, 16 studies satisfied our eligibility criteria. The results suggest that CBD modulates γ-Aminobutyric acid and glutamate signaling in the basal ganglia and dorso-medial prefrontal cortex. Furthermore, CBD regulates activity in regions associated with mesocorticolimbic reward pathways; salience, limbic and fronto-striatal networks which are implicated in reward anticipation; emotion regulation; salience processing; and executive functioning.Conclusion CBD appears to modulate neurotransmitter systems and functional connections in brain regions implicated in AUD, suggesting CBD may be used to manage AUD symptomatology.

96-week retention in treatment with extended-release subcutaneous buprenorphine depot injections among people with opioid dependence: Extended follow-up after a single-arm trial.

BACKGROUND: The most recent formulation of buprenorphine treatment is extended-release depot injections (BUP-XR) that are administered subcutaneously by health care professionals. This study aimed to observe treatment outcomes of BUP-XR delivered in standard practice during a 96-week follow-up period in a community setting. METHODS: This study is an extension of the CoLAB study, a prospective single-arm, multicentre, open label trial (N=100, 7 sites in Australia) among people with opioid dependence who received monthly injections of BUP-XR to evaluate the retention in treatment. Participants were followed for 96 weeks, comprising 48 weeks of the CoLAB study followed by a 48-week extension. RESULTS: Of 100 participants at baseline, 47 were retained on BUP-XR at 96 weeks. The median time retained on monthly depot was 90 weeks. Heroin use (adjusted OR=0.19, P=0.012) in the month prior to baseline was associated with lower odds of retention on BUP-XR. Older age at first opioid use (adjusted OR= 1.08, P=0.009) and longer duration in OAT at baseline (adjusted OR= 1.12, P=0.001) were associated with increased retention. Prevalence of past four-weeks opioid use was estimated at 4% at 96 weeks of treatment (prevalence 0.04, 95%CI: 0.00-0.11) compared to 15% at baseline. Quality of life and medication treatment satisfaction improved over time for those retained in treatment. CONCLUSION: This is one of the few studies to describe long term (96 week) retention in treatment with BUP-XR in a community setting. It displayed retention rates with 47% of participants completing 96 weeks of treatment with BUP-XR. Patient reported outcomes suggest improvements in client wellbeing. FUNDING: Indivior.

A phase III multisite randomised controlled trial to compare the efficacy of cannabidiol to placebo in the treatment of cannabis use disorder: the CBD-CUD study protocol.

BACKGROUND: Cannabis use disorder (CUD) is increasingly common and contributes to a range of health and social problems. Cannabidiol (CBD) is a non-intoxicating cannabinoid recognised for its anticonvulsant, anxiolytic and antipsychotic effects with no habit-forming qualities. Results from a Phase IIa randomised clinical trial suggest that treatment with CBD for four weeks reduced non-prescribed cannabis use in people with CUD. This study examines the efficacy, safety and quality of life of longer-term CBD treatment for patients with moderate-to-severe CUD. METHODS/DESIGN: A phase III multi-site, randomised, double-blinded, placebo controlled parallel design of a 12-week course of CBD to placebo, with follow-up at 24 weeks after enrolment. Two hundred and fifty adults with moderate-to-severe CUD (target 20% Aboriginal), with no significant medical, psychiatric or other substance use disorders from seven drug and alcohol clinics across NSW and VIC, Australia will be enrolled. Participants will be administered a daily dose of either 4 mL (100 mg/mL) of CBD or a placebo dispensed every 3-weeks. All participants will receive four-sessions of Cognitive Behavioural Therapy (CBT) based counselling. Primary endpoints are self-reported cannabis use days and analysis of cannabis metabolites in urine. Secondary endpoints include severity of CUD, withdrawal severity, cravings, quantity of use, motivation to stop and abstinence, medication safety, quality of life, physical/mental health, cognitive functioning, and patient treatment satisfaction. Qualitative research interviews will be conducted with Aboriginal participants to explore their perspectives on treatment. DISCUSSION: Current psychosocial and behavioural treatments for CUD indicate that over 80% of patients relapse within 1-6 months of treatment. Pharmacological treatments are highly effective with other substance use disorders but there are no approved pharmacological treatments for CUD. CBD is a promising candidate for CUD treatment due to its potential efficacy for this indication and excellent safety profile. The anxiolytic, antipsychotic and neuroprotective effects of CBD may have added benefits by reducing many of the mental health and cognitive impairments reported in people with regular cannabis use.

Interconnections between unintended pregnancy, alcohol and other drug use, and pregnancy, birth, infant, childhood and socioeconomic outcomes: a scoping review.

BACKGROUND: Unintended pregnancy (UIP) and substance use disorder share underlying root causes with similar impacts for women and their offspring in pregnancy, birth and beyond. Furthermore, intoxication with alcohol and other drugs (AOD) increases the risk of UIP. OBJECTIVES: To assess the available evidence on associations between UIP and health, social and economic outcomes, in women who use AOD. SEARCH STRATEGY: The review utilised the Joanna Briggs Institute Methodology for Scoping Reviews and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) reporting guidelines. The search was conducted across multiple databases, including Scopus and Medline, and limited to studies published between January 2000 to June 2023. SELECTION CRITERIA: Studies reporting on interactions between AOD use and UIP, and pregnancy, birth, infant, childhood, social or economic outcomes. All patterns and types of AOD use, except isolated use of tobacco, were included. Studies were available in English and conducted in high-income countries. DATA COLLECTION AND ANALYSIS: Selected articles were reviewed, and data collected by two independent reviewers using a standardised data extraction sheet. Findings were summarised and reported descriptively. MAIN RESULTS: A total of 2536 titles and abstracts were screened, 97 full texts were reviewed, and three studies were selected for inclusion in the scoping review. There was heterogeneity in types and patterns of AOD use, differences in study design and tools to assess pregnancy intention, and each focused on disparate outcomes. No study assessed or reported on birth outcomes. CONCLUSION: There is a paucity of data examining the intersection between AOD use and UIP and further research is needed.

Differences in prescribed medicinal cannabis use by cannabinoid product composition: Findings from the cannabis as medicine survey 2020 (CAMS-20) Australia-wide study.

INTRODUCTION: Prescribed medicinal cannabis (MC) is an increasingly common prescription in Australia for treating pain, anxiety, and sleep disorders. Prescribed MC products generally contain tetrahydrocannabinol (THC) and/or cannabidiol (CBD) in a variety of dose levels and forms. It is unclear whether THC and CBD products are used by patients with different characteristics and for different conditions. OBJECTIVES: To examine consumer experiences of using THC- and CBD-containing prescribed MC products to better understand how they are being used within the Australian context. METHODS: We utilised data collected from an online anonymous cross-sectional survey of individuals (CAMS-20 survey), consisting of Australian residents using cannabis for therapeutic reasons. We focused on a subgroup of participants (N = 546) receiving prescribed MC products. We utilised linear, logistic, and multinomial regression modelling to analyse responses to survey questions based on the cannabinoid profile of the prescribed product. RESULTS: Participants prescribed THC-dominant MC products were statistically more likely to be younger, male, and to prefer inhaled routes of administration than participants using CBD-dominant products who were older, female, and preferred oral routes of administration. Pain and mental health were the most common reasons for all types of prescribed MC, but were more likely to be treated with THC than CBD despite the significantly higher risk of mild to severe drowsiness, dry mouth and eye irritation. Consumer reported effectiveness of prescribed MC was very positive, particularly for THC-containing products. Consumers on opioids and antipsychotics were statistically more likely to be prescribed THC-containing products than products containing CBD only, despite the greater risk of impairment. CONCLUSIONS: This Australia-wide study found clear differences in consumer-reported experiences of prescribed THC- and CBD-containing products. Current prescriptions of these products do not always align with relevant clinical guidance. Educating prescribers around cannabinoid products is essential to ensure optimal prescribing practices and to prevent avoidable drug side effects and interactions.

The impact of changes in opioid dependency treatment upon COVID-19 transmission in Sydney, Australia: a retrospective longitudinal observational study.

BACKGROUND: In April 2020, in response to the COVID-19 public health emergency, South Eastern Sydney Local Health District (SESLHD) Drug and Alcohol services modified their delivery of opioid dependency treatment (ODT) to reduce spread of COVID-19 and maintain continuity of care by increasing use of takeaway doses (TADs), transferring clients to local community pharmacies for dosing and encouraging the use of long-acting depot buprenorphine (LADB) which enabled once a month dosing. METHODS: This study was a retrospective longitudinal case-control study conducted from August 1st, to November 30th, 2021. Eligible clients were those admitted for treatment with SESLHD ODT Services prior to August 1st,2021 and who remained in treatment beyond November 30th, 2021. COVID-19 diagnoses were determined by a COVID-19 PCR and extracted from the electronic Medical Records (eMR) Discern Reporting Portal. Demographic, clinical and dosing related data were collected from eMR and the Australian Immunisation Register (AIR). RESULTS: Clients attending SESLHD ODT services had significantly greater odds of acquiring COVID-19 than the NSW adult population at large (OR: 13.63, 95%CI: 9.64,18.88). Additionally, amongst SESLHD ODT clients, being of Aboriginal and Torres Strait Islander origin was associated with greater odds of acquiring COVID-19 (OR = 2.18, CI: 1.05,4.53); whilst being employed (OR = 0.06, CI:0.01,0.46), receiving doses at pharmacy (OR = 0.43, CI: 0.21,0.89), and being vaccinated (OR = 0.12, CI: 0.06,0.26) were associated with lower odds. Every additional day of attendance required for dosing was associated with a 5% increase in odds of acquiring COVID-19 (OR = 1.05, CI: 1.02,1.08). CONCLUSIONS: Clients attending SESLHD ODT services are significantly more likely to acquire COVID-19 than the NSW population at large. Promoting vaccination uptake, transferring clients to pharmacy, and reducing the frequency of dosing (by use of takeaway doses or long-acting depot buprenorphine) are all potential methods to reduce this risk.

Understanding the research capacity of alcohol and other drugs services in New South Wales, Australia.

INTRODUCTION: Enhancing health system research capacity can support improved quality care. This study assessed the research capacity of public local health district (LHD) and non-government organisation (NGO) alcohol and other drug (AOD) services, at the organisational, team and individual level. Research barriers and motivators were also examined. METHODS: Staff from LHD and NGO AOD treatment services in New South Wales completed an online survey using the Research Capacity and Culture (RCC) tool. Overall median research capacity scores are presented for the RCC subscales (organisational, team and individual). Comparisons were conducted by service type (LHD/NGO), geographical location (metropolitan/rural) and affiliation with a research network (yes/no). Qualitative questions explored barriers and motivators to research at individual and team levels. RESULTS: Of 242 participants, 55% were LHD-based and 45% NGO-based. Overall RCC scores indicated moderate research capacity at all levels. Organisational capacity (Med = 6.50, interquartile range [IQR] = 3.50) scored significantly higher than the team (Med = 5.00, IQR = 6.00) and individual level (Med = 5.00, IQR = 4.25). No differences in RCC scores existed between NGOs and LHDs. Metropolitan AOD services scored higher research capacity at the organisational level (Med = 7.00, IQR = 3.00) than rural services (Med = 5.00, IQR = 5.00). LHDs affiliated with a research network scored significantly higher at the organisational, team and individual level than non-affiliated LHD services. Key research barriers were inadequate time and funding. Motivators included skill development and problem-identification requiring change. DISCUSSIONS AND CONCLUSIONS: AOD services in New South Wales have moderate research capacity. Identified barriers and motivators can be used to target responses that enhance capacity and improve treatment outcomes.

Driving-related behaviors, attitudes, and perceptions among Australian medical cannabis users: results from the CAMS 20 survey.

Road safety is an important concern amidst expanding worldwide access to legal cannabis. The present study reports on the driving-related subsection of the Cannabis as Medicine Survey 2020 (CAMS-20) which surveyed driving-related behaviors, attitudes, and perceptions among Australian medical cannabis (MC) users. Of the 1063 respondents who reported driving a motor vehicle in the past 12 months, 28% (297/1063) reported driving under the influence of cannabis (DUIC). Overall, 49-56% of respondents said they typically drive within 6 h of MC use, depending on the route of administration (oral or inhaled). Non-medical cannabis (NMC) was perceived to be more impairing for driving than MC. Binary logistic regression revealed associations between likelihood of DUIC and (1) inhaled routes of cannabis administration, (2) THC-dominant products, (3) illicit rather than prescribed use, (4) believing NMC does not impair driving, and (5) not being deterred by roadside drug testing. Overall, these findings suggest there is a relatively low perception of driving-related risk among MC users. Targeted education programs may be needed to highlight the potential risks associated with DUIC, and further research is needed to determine whether driving performance is differentially affected by MC and NMC.

A systematic review on the effect of routine outcome monitoring and feedback on client outcomes in alcohol and other drug treatment.

ISSUES: Routine outcome monitoring (ROM) involves regularly measuring clients' outcomes during treatment, which can then be fed back to clinicians and/or clients. In the mental health field, ROM and feedback have been shown to improve client outcomes; however, no systematic reviews have examined whether improvement is also seen in alcohol and other drug (AOD) treatment outcomes. This review examines whether feedback to clients and/or clinicians of ROM data in AOD treatment improves future client outcomes. APPROACH: This systematic review of papers identified in Medline, PsycInfo and Scopus examines the effect on client outcomes of feeding back ROM data to clinicians and/or clients in AOD treatment settings. Key client outcomes included substance use, treatment attendance and wellbeing measures. KEY FINDINGS: Ten studies were included-five randomised controlled trials and five pre-post within-subjects designs. Six studies were deemed good- or fair-quality. Of these six, three provided feedback to clinicians only, one to clients only, and two to both clients and clinicians. Only one of the six found feedback was associated with significant reductions in substance use and only among off-track clients. Four of the six found feedback improved other outcomes, including treatment retention, global functioning, therapeutic alliance and mood symptoms. CONCLUSIONS: There may be some positive effects for clients of providing feedback to clients and/or clinicians; however, the small number of randomised trials and the heterogeneity of methods, outcome measures and findings, mean that firm conclusions cannot be drawn about the efficacy of feedback until larger randomised studies are conducted.

Substance use, socio-demographic characteristics, and self-rated health of people seeking alcohol and other drug treatment in New South Wales: baseline findings from a cohort study.

OBJECTIVE: To investigate the demographic characteristics, substance use, and self-rated health of people entering treatment in New South Wales public health services for alcohol, amphetamine-type stimulants, cannabis, cocaine, or opioids use, by principal drug of concern. DESIGN: Baseline findings of a cohort study; analysis of data in patient electronic medical records and NSW minimum data set for drug and alcohol treatment services. SETTING, PARTICIPANTS: People completing initial Australian Treatment Outcomes Profile (ATOP) assessments on entry to publicly funded alcohol and other drug treatment services in six NSW local health districts/networks, 1 July 2016 - 30 June 2019. MAIN OUTCOME MEASURES: Socio-demographic characteristics, and substance use and self-rated health (psychological, physical, quality of life) during preceding 28 days, by principal drug of concern. RESULTS: Of 14 087 people included in our analysis, the principal drug of concern was alcohol for 6051 people (43%), opioids for 3158 (22%), amphetamine-type stimulants for 2534 (18%), cannabis for 2098 (15%), and cocaine for 246 (2%). Most people commencing treatment were male (9373, 66.5%), aged 20-39 years (7846, 50.4%), and were born in Australia (10 934, 86.7%). Polysubstance use was frequently reported, particularly by people for whom opioids or amphetamine-type stimulants were the principal drugs of concern. Large proportions used tobacco daily (53-82%, by principal drug of concern group) and reported poor psychological health (47-59%), poor physical health (32-44%), or poor quality of life (43-52%). CONCLUSIONS: The prevalence of social disadvantage and poor health is high among people seeking assistance with alcohol, amphetamine-type stimulants, cannabis, cocaine, or opioids use problems. Given the differences in these characteristics by principal drug of concern, health services should collect comprehensive patient information during assessment to facilitate more holistic, tailored, and person-centred care.
